SPECIFICATION formingpart of Letters Patent No. 758,008, dated April 19,1904.

Application filed J1me 1903- To ctZZ whom it may concern:

Be it known that I, PARKER D. HEATHER, a citizen of the United States,residing at Pontiac, in the county of Oakland and State of Michigan,have invented certain new and useful Improvements in Cots, of which thefollowing is a specification.

This invention relates to furniture having a spring-support, the purposebeing to provide novel means for sustaining the fabric and to preventcareening or swaying of the springs when subjected to perpendicularpressure or strain about at a right angle to the plane of the support.

The invention is particularly designed for cots, couches, chairs, andlike articles of furniture intended to support the person in either asitting or recumbent position.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand draw ings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which Figure 1is a vertical central longitudinal section of a cot illustrating theapplication of the invention. Fig. 2 is a transverse section about onthe lineX X of Fig. 1, the parts being on a larger scale and theintermediate portion broken away. Fig. 3 is a detail perspective viewshowing more clearly the supporting and guiding means for the springsand covering. Fig. 4 is a detail perspective view of the component partsof the guide, the same being separated.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The relatively fixed section of the cot or like article is indicated at1 and the adjustable section at 2, the latter being hinged to theformer. Each section comprises a frame 3, supporting-springs 4, and acovering 5, the

laced and confine the lower coils of the springs 4, as shown mostclearly in Fig. 4. Strips or slats 7 rest upon the springs 4 and may beattached thereto and are adapted to sustain the covering or fabric 5 atdesired points. Clampstrips 8 are secured to the slats 7 by suitablefastenings and confine the fabric 5 thereto.

The strips 7 act as stays and equalize the pressure or load upon thesprings, thereby preventing undue straining of the fabric 5 when loadedat one point.

An essential feature ofthe invention is to insure movement of the slatsor strips 7 in straight lines and in a direction at a right angle to theplane of the fabric 5. In order to attain this object, guides of novelconstruction are interposed between the parts 7 and elements of theframe 3 and cooperate th erewith. The guide means consists, essentially,of a socket-plate 9 and a ribbed bracket 10. The socket-plate 9 isprovided with parallel flanges 11, curved toward each other at theirouter ends and inclosing guide-space 12 to receive the rib 13 at thevertical edge of the bracket 10, said rib 13 having a head 14 at itslower end to limit the upward movement of the bracket 10 with referenceto the socket-plate 9. The parts 9 and 10 are firmly attached to therespective parts 3 and 7 by any suitable fastening means. These parts 9and 10 may be constructed in any commercial manner, either by beingcast, drop-forged, or struck up from sheet metal.

In the adjustment of the parts the upper ends of the springs 4 projectabove the plane of the upper edge of the frame 3. Hence the fabric 5normally occupies a position above the plane of frame 3, and its endportions are drawn downward and secured to opposite bars of the frame,as shown most clearly in Fig. 1.

nected with and upheld by said frame, a sup- Any Weight or strain comingat a right angle upon the fabric will cause the springs to contract in adirection at a right angle to the plane of said fabric, this being dueto the guide devices 9 and 10 applied in the manner stated. It will thusbe seen that the full benefit of the tension of the springs is obtained,and said port sustainedby said springs, and means for directing thecoil-springs when contracting and expanding, said means consisting of asocket-plate havingparallel flanges curved toward each other at theirouter edges and a bracket having a rib slidably mounted in the spaceformed between the flanges of the socketplate and having'a head at oneend of the rib and an arm at the opposite end to positively limit themovements of the bracket in each direction, said slidable bracket havingthe aforesaid support attached thereto, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
